4 Claims. (Cl. 292263) This invention relates to a sill window adjusting device, particularly for opening storm sash and holding them secure in opened or closed position. This application is a continuation in part of our application filed February 13, 1950, Serial No. 143,882, and now abandoned.

There are a substantial number of adjusting devices to be mounted on the side frames of a window for opening or closing storm sash. It has been'found that a substantial number of these devices rely upon a friction means for their effective operation in holding a storm sash in opened position or in closed position. When these devices are loosened through wear their principal effectiveness is gone and they fail to hold a storm sash securely in position free from rattling, and the devices themselves tend to cause similar disturbance. It is desirable therefore to have an adjusting device to hold a storm sash in opened or closed position which is not dependent upon the action of friction for its effective operation but will operate effectively for an indefinite period of time. It is also desirable to have an adjusting device for opening or closing a storm sash which may be mounted on the sill of a window so that only a single unit is necessary instead of the use of a pair of units such as are required when an opening device is secured to each side of a window frame.

It is therefore an object of this invention to provide a sill window adjusting device which will hold a storm sash securely in closed or opened position without the use of any friction means.

It is another object of this invention to provide a sill window adjusting device comprising a pair of brackets respectively secured to the sill of a window and the bottom rail of a storm sash and a pair of linked members having their ends respectively pivotally secured to said brackets whereby when said linked members are in extended position just below a dead center position said storm sash will be locked in opened position.

It is another object of this invention to provide a sill window adjusting device comprising a pair of brackets respectively secured to the sill of a window frame and the bottom rail of a storm sash, a pair of linked members pivoted together at their adjacent ends, the outer ends of said linked members being respectively secured to said brackets, and means for limiting the extended position of said links to a point just below their dead center position whereby said storm sash will be locked in opened position.

It is a further object of this invention to provide a sill Window adjusting device comprising a pair of brackets respectively secured to the sill of a window and the bottom rail of a storm sash at approximately the midpoint of each, a plate link member having one end adapted to be pivoted to said sill bracket and having a loop formed at its other end, a U-shaped link having its closed end disposed in said loop and having its open end portions pivoted to said sash bracket, and an upstanding lug at the outer end of said sill bracket to limit the downward movement of said plate link member whereby said plate n mb r is e in a Po ion just below dead center e 2,791,456 Patented May 7, 1957 when in outward extended position, and said second mentioned link member is adapted to overlie said first mentioned link member and both link members overlie said sill bracket when said device is in a closed position and said links will be in a position just below dead center to hold said storm sash locked in a closed position.

It is more specifically an object of this invention to provide a sill window adjusting device such as described in the previous object, said second mentioned link having its open end portion resiliently removably held in said sash bracket.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which:

Fig. 6 is a plan view of another modification of applicants device with some parts in dotted line; and

Fig. 6a is a view in partial vertical section taken on line 6a--6a of Fig. 6, as indicated by the arrows.

Referring to the drawing, applicants device is shown comprising brackets 10 and 11. Said brackets are substantially rectangular in plan and may be made of any suitable sheet material and are made preferably from a sheet material which can be easily stamped out and which is not subject to rust or other deterioration from the weather or which may be easily coated to resist such deterioration. Said brackets will have base portions 10a and 11a, each having a pair of openings 10b and 11b therein centrally thereof through which screws may be placed to hold the same in operating position. Said members 10 and 11 have upstanding side portions 10c and 11c. Said side portions are here shown as being substantially triangular in form. Pairs of horizontally alined openings 10d and 11d respectively are provided in said upstanding portions. Said member 10 has an upstanding lug portion 10e extending across its outer end. A plate member 13 is provided having a central portion 13a substantially rectangular in plan and having an inner end portion reversely turned to form a loop 13b. Said member 13 will be of a width substan tially the same as the width or distance between the upstanding portions of said member 10. Said loop portion 13b will be disposed between said upturned portions of member 10 in alinement with said openings 10d. A pin 14 is provided which is disposed through said openings 10d and through said loop 13b therebetween. Said pin 14- may be secured in position by having its outer ends somewhat enlarged by being flattened whereby said member 13 is securely pivoted to said member 10. Said member 13 has an outer end portion of reduced width reversely bent to form a loop 13c. Said plate member 13 will have openings 13d therein which will be in alinement with openings 10b when said member 13 overlies said member 10.

A member 15 is provided. Said member 15 is preferably made of resilient wire or rod-like material of small transverse dimension and is formed into a generally U-shaped member. Said member 15 has a closed end portion 15a which is disposed in loop 13c. Said member 15 has side portions 15b of some length. The outer end portions 150 of said sides 15b are inclined slightly away from each other and the ends 15d are turned out: wardly at right angles to said sides 15b. Said ends 15d are disposed in openings lid. The sides 15b will be spaced apart for a distance somewhat greater than the width of said member 11 whereby when said ends 15d are disposed in the openings 11d, said sides 15b will be under some degree of tension.

Said lug c extends upwardly t-oa point whereby when said applicants device is in extended operating position, as is shown in Fig. 2, said member 13 will be stopped at a point justbelow its dead center position in its relation to member 15.

Referring to Fig. 1, applicants device is shown in operating position with bracket 11 secured to the bottom rail 18:: of a storm sash 18. Said bracket 10 is shown secured to a sill 19. In closed position said member will overlie said member 13 and said member 13 will be in a position just below its dead center position overlying portion 10a and thus will be in a locked position. A broken away portion of a window frame is shown supporting said sash 18 and said sill 19. A portion of a window sash 21 is shown. I

Referring to Fig. 2, applicants device is shown in extended operating position holding said storm sash 18 in opened position. Said member 13 will be held in a position just below its dead center position in relation to member 15 by said upstanding lug or stop member 10c. Said member 13 will be locked in this position.

In operation, bracket 10 will be secured as by screws to the central portion of the sill of a window frame. Said bracket 11 will be secured to the bottom rail of a storm sash tobe used in said window frame and said brackets will be in alinement. The link members 13 and 15 are permanently secured together and said member 13 is permanently pivotally secured to said member 10. Member 15 is quickly and easily pivoted to member 11 by having its side portions 15b pressed together and having its end portions 15d disposed in openings 11d of said member 11. Thus said member 15 is held in position pivoted to member 11 by tension and is therefore easily secured thereto or removed therefrom. When applicants device is in extended operating position to hold a storm sash in opened position, said plate member 13 will rest on said upstanding lug 100 at a point just below its dead center position relative to member 15. In this position applicants device is in a locked position securely holding said sash in opened position whereby it is not subject to movement by the action of wind either inwardly or outwardly. To close said storm sash, the operator need only place his hand beneath said members 13 and 15 and lift upwardly to break the toggle formed by said members 13 and 15 whereby said member 13 will move rearwardly to overlie said member 10, and said member 15 will overlie said member 13. Said member 13 will rest in a position below its dead center position whereby said storm sash 18 will be securely locked in closed position.

One of said brackets 11 may be secured to a window screen, which screen may be used to replace said storm sash during the Warm months of the year. It is seen that applicants device is easily attached or detached by simply pressing together said members 15b and said ends 15:] will be Withdrawn from said opening 11d.

A modification of a portion of applicants device is disclosed in Fig. 5. A portion of a link plate member 13' is shown which is identical in all respects to said member 13 in having a central portion 13a, an outer loop portion 13'c and apertures 13zi. Said member 13' differs from member 13 in having lug portions 13'e extend outwardly of portion 13'a adjacent either side of loop 13ft: to apeint just beyond the cadet said loop.- A link member 15' is provided identical in structure to said member 15. Said lug portions 13'e are in a plane whereby they will be engaged by sides of member 15' when said members 13 and 15 are in a position just below their dead center position.

In operation, when said members 13' and 15 are in extended positions as are members 13 and 15, as shown 1 in Fig. 3, said lug I'lle will act as a stop for member 13 and said lug portions 13'e will be engaged by the sides of member 15' and act as an additional stop when said members 13 and 15 are in a position just below their dead center position and said members will be locked in said position and hold a storm sash securely in an open position until the toggle formed by said members 13 and 15 is broken by raising said members upwardly.

A further modification of applicants device is shown in Fig. 6. A sill bracket 10" is provided identical in all respects to said member 10 except that it does not have an upstanding lug portion such as lug portion 102 at its outer end. A plate link member 13" is provided identical in structure to said member 13' having a central portion 13"a, an inner loop portion 13"b journaled in member 10", an outer loop portion 13"c, spaced apertures 13"d and extended lug portions 13"e. A link member 15 is provided pivoted to said loop 13"c and identical in structure to said member 15.

'In operation, when members 13" and 15" are in extended position, said lug portions 13"e will be engaged by the sides of member 15" when said members 13" and 15 are in a position just below dead center. Hence said members 13" and 15" will be locked in said extended position. In all other respects the operation is as described above.

Thus it is seen that we have provided a sill window adjusting device of very simple construction which is easily placed in operating position and which is very easily attached to or detached from a storm sash or a window screen, and which will maintain its operating efficiency indefinitely as there is no foreseeable wear of any of the parts which will affect the operating efiiciency of applicants device. Applicants device is being produced on a commercial scale and has proved to be very successful in use.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which, generally stated, consist-s in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims.
